Abstract (en)

[origin: US6366037B1] A separately excited electric machine has a rotor and a stator and a device for detecting the rotational position of the rotor relative to the stator. A position determination device is provided for determination of the rotational position by evaluation of a signal which can be tapped at the pole winding circuit and is imprinted by pole winding inductivities exhibiting rotational position dependency. The pole winding circuit has phase strands that are star-connected, and the position determination device is provided for evaluating the potential at the star point during motor operation of the machine.
